I'm going to argue that caffeine pills are a huge money saver.
I am a caffeine addict -- not doubt about it. I love, love, love my morning coffee. However, if I'm caught on the run, or I forgot to make coffee at home, I'm refuse to stop somewhere and fork out a few bucks for coffee that'll probably suck anyway.
A bottle of 100, 200 mg, tablets is around $7. So at 7 cents a (big) dose, you can avoid the lines, the sucky coffee, the risk of spilling it down your shirt (we're rushing, remember?), and the environmental waste of a single-use container. With a cup* of coffee having around 45mg of caffeine, a split tablet would be roughly comparable your typical 12 oz coffee *(a 'cup' of tea or coffee is strangely 6 oz, not 8 oz...also it's worth noting there's huge variation in caffeine content within coffee). By around the third time you've tried this trick, it's already paid for itself.
Sure, you could grin and bear it - but feeling dimwitted with a slight headache doesn't seem really badass to me. I don't like taking a Tylenol or Advil for the headache and I'd still be cognitively duller until I have my fix (the first step is admitting you have a problem). I'd much prefer the days when I can take my time and enjoy my coffee - but when that doesn't happen, that has saved my hide a couple times.
